Answer 1

Asexual reproduction results in two organisms with the same parent and the same DNA.

Asexual reproduction produces offspring which are genetically identical to the parent because the offspring are all clones, that is, identical copies of the original parent.

Asexual reproduction in animals occurs through various process such as fission, fragmentation, budding and parthenogenesis. A single individual can produce offspring asexually and large numbers of offspring can be produced quickly with asexual reproduction.

A new potato growing from an old potato can be an example of asexual reproduction. Variation is not possible or significantly reduced in asexual reproduction. Asexual reproduction results in offspring with the same combination of genetic information as the parents.

4. which parts of the amino acids x and y are involved in the formation of a peptide bond between them? assume that w is the first amino acid in the polypeptide chain, x is the second, and y is the third.

Answers

In a polypeptide chain, to generate an amide, the peptide bond connects the carboxyl group of one amino acid (x) to the amino group of the subsequent amino acid (y).

A polypeptide chain is defined as a series of amino acids linked together by peptide bonds. Poly stands for numerous, while peptide stands for protein. A polypeptide chain is therefore a chain of protein or amino acid building components. Polypeptide chains are crucial because they are the building blocks of proteins.

The carboxyl group of the first amino acid, w binds with the amino group of the next amino acid, x. The carboxyl group of x binds with the amino group of the y amino acid. Thus, peptide bonds are formed between the w-x-y amino acids making them a polypeptide chain.

when 56.6 g of calcium is reacted with nitrogen gas, 31.0 g of calcium nitride is produced. what is the percent yield of calcium nitride for this reaction? 3ca(s) n2(g)→ca3n2(s)

Answers

Calculation of percent yield requires the theoretical yield to be calculated first. Using that method, the percent yield of the reaction is 44%.

To calculate the percent yield of calcium nitride, we first need to calculate the theoretical yield. To do this, we need the molar mass of both calcium (40 g/mol) and calcium nitride (3 * 40 + 2 * 14) g/mol = 148 g/mol.

3 moles of calcium produce 1 mol of calcium nitride so the proportion we can make will look like this:

120 g of calcium : 148 g of calcium nitride = 56.6 g of calcium : X

X = 148 g of calcium nitride * 56.6 g of calcium / 120 g of calcium

X = 69.8 g of calcium nitride

This is the theoretical yield. Calculating the percent yield works like this - we divide the actual mass by the theoretical yield and then multiply that number (that is always supposed to be between 0 and 1) by 100%:

%yield = 100% * 31.0 g / 69.8 g = 44%

Heat can bring about chemical reactions and chemical reactions can produce heat. is this also true for light and heat? give an example to illustarte each case.

Answers

Yes, there are chemical reactions that are brought about through the use of light (such as free radical halogenation) and there are chemical reactions that produce light (chemiluminescence).

Numerous reactions use light as an initiator. For example, in various examples of free radical halogenation (a reaction between a hydrocarbon and a halogen molecule, where alkyl halides are formed), light is needed to break the bond between the bromine atoms in order to form bromine radicals that then initiate the chain reaction leading to the formation of the product.

The phenomenon of producing light through a chemical reaction is called chemiluminescence. It is relatively rare, but not unheard of. One example is the reaction between luminol and hydrogen peroxide, which forms 3-aminophthalate and releases light.

Calculate the % yield of the rection between 6.00 grams of salicylic acid and excess acetic anhydride to form 3.12 grams od Aspirin:

Answers

Answer:

You identify the limiting reactant by calculating the moles of product that can be formed from each reactant.

Explanation: Then you calculate the theoretical yield of product from the amount of the limiting reactant.

EXAMPLE Aspirin is prepared by the reaction between acetic anhydride and salicylic acid.

acetic anhydride + salicylic acid → aspirin + acetic acid

C 4 H 6 O 3 + C 7 H 7 O 3 → C 9 H 8 O 4 + C 2 H 4 O 2 m m A m l + m B m m → m l l C m l l + m l D

What is the theoretical yield of aspirin ( C ) if you reacted 4.32 g of acetic anhydride ( A ) with 2.00 g of salicylic acid ( B )?

Solution :

The molar masses are

Acetic anhydride = A = C 4 H 6 O 3 = 102.1 g/mol

Salicylic acid = B = C 7 H 6 O 3 = 138.1 g/mol

Aspirin = C = C 9 H 8 O 4 = 180.2 g/mol

Identify the limiting reactant We calculate the moles of each reactant and then use the molar ratios from the balanced equation to calculate the moles of aspirin.

Moles of aspirin from A = 4.32 g A × 1 mol A 102.1 g A × 1 mol C 1 mol A = 0.0423 mol C

Moles of aspirin from B = 2.00 g B × 1 mol B 138.1 g B × 1 mol C 1 mol B = 0.0145 mol C B gives the smaller amount of aspirin, so B is the limiting reactant.

Calculate the theoretical yield 0.0145 mol C × 180.2 g C 1 mol C = 2.61 g C

suppose you did not want to calculate the precise atomic mass for one of the elements, such as nitrogen or oxygen. how could you approximate the value of the atomic mass?

Answers

The atomic mass of every element may be simply calculated using the number of protons and neutrons in the nucleus.

The atomic mass can be approximated by summing the number of protons and neutrons in the atom. The average mass of an element's atoms that are meaningfully measured in the atomic mass unit (amu) is defined as its atomic mass. It should be noted that the atomic mass is calculated by adding the masses of all the element's isotopes. This is the most precise method for calculating the relative atomic mass.

However, if we do not wish to compute the precise atomic mass of one of the elements, we may simply sum the number of protons and neutrons in the atom. This provides us a ballpark estimation of the atom's mass. Another way for estimating the atomic mass of any element is to simply double the value of the atomic number that is known for each individual element.

Answers

The molarity of a solution is 3.743M.

Molarity of a solution:

Molar concentration is a measure of the concentration of a chemical species, in particular of a solute in a solution, in terms of the amount of substance per unit volume of solution.

The formula for the molarity of a solution:

M = [tex]w_{B}[/tex] × 1000 / [tex]M_{B}[/tex] × V(ml)

[tex]w_{B}[/tex] = 50.54g

[tex]M_{B}[/tex] = molecular mass of water(H2O) = 2 + 16 = 18

V = Volume = 750ml

Putting the value in the equation, we get

M = 50.54 ×1000 / 18 × 750

   = 50540 / 13500

    = 3.743M

Therefore the molarity of a solution is 3.743M

Answers

The average atomic mass of the given isotopes of Halfnium is 178.55 amu

The average atomic mass of an element is equal to the sum of its isotope masses multiplied by it's own natural abundance (the decimal associated with the percent of atoms of that element for a given isotope).

In order to determine the weighted average, we must consider the % natural abundances of each isotope. The atomic mass of an element is the weighted average of the atomic masses of the element's naturally occurring isotopes. Determine the average atomic mass by using atomic masses and percentage abundances of each isotope. To convert each percentage abundance to decimal form, divide it by 100. Multiply this figure by the atomic mass of the isotope. To get the average atomic mass, add the atomic masses of each isotope together.

To determine the average atomic mass of Halfnium, the mass fractions of the isotopes multiplied by their respected atomic masses must all be added.

Using 100 atoms as the basis, calculate the mass fractions (m1, m2,...m5):

m1 =   5/100 = 0.05

m2 = 19/100 = 0.19

m3 = 27/100 = 0.27

m4 = 14/100 = 0.14

m5 = 35/100 = 0.35

Multiplying the mass fractions with the atomic masses of the respective isotopes.

Average atomic mass of Halfnium is:

Avg = (m1 x 176) + (m2 x 177) + (m3 x 178) + (m4 x 179) + (m5 x 180)

Avg = (0.05 x 176) + (0.19 x 177) + (0.27 x 178) + (0.14 x 179) + (0.35 x 180)

Avg = 178.55 amu

Answers

The number of milliliters of 3.0m NaOH required to react with 0.5g of Cu2+ to form Cu(OH)2 is 5.249 ml

The reaction is as follows;

2NaOH  + Cu2+  ------------> Cu(OH)2  +  2Na+

From the balanced chemical reaction, 0.5 g of Cu2+ = 0.5/63.5 = 7.874x10-3 moles  (molar mass of Cu2+ = 63.5 g)

Thus, moles of NaOH required = 2*moles of Cu2+ = 0.01575

If an Oreo cookie is 0.69 cm thick (1 cookie = 0.69 cm), how many Oreos does it take to reach the moon if the moon is 3.84 x 10^8 m away from earth?

Answers

It takes 5.89 x 10¹⁰ Oreos to reach the moon.

The average distance from the Earth to the moon is 385 000.6 km.

Metres = 385 000.6 km × (1000 m/1 km ) = 385 000 600 m

Centimetres = 38 500 060 000 m × (100 cm/1 m) = 38 500 060 000 cm

Oreos = 38 500 060 000 cm × (1 Oreo/0.654 cm) = 58 900 000 000 Oreos

= 5.89 x 10¹⁰ Oreos

Its diameter is around one-quarter that of the Earth (comparable to the width of Australia). The Moon is the Solar System's fifth-largest satellite. It is the largest (and most massive) satellite relative to its home planet and is larger than any other known dwarf planet. [f] According to geophysical criteria, the Moon is a planetary-mass object that became a differentiated rocky body, making it a satellite planet. There is no atmosphere, hydrosphere, or magnetic field. Its surface gravity is around one-sixth that of Earth (0.1654 g). Io, Jupiter's moon, has the highest surface gravity and density of any satellite in the Solar System.
